DHT11 and DHT22 comparison

In this example I wanted to compare the readings of a DHT11 and a DHt22 (AM2032) temperature sensor. The sensors were positioned side by side with the same length of wire connecting them to my Arduino. Basically i was keeping the conditions as similar as possible.

This also shows how to connect 2 of these types of sensors.
The DHT11 costs about $1 using the links at the bottom, the DHT22 costs $5. So as you can see there is also a price difference that you may consider.

Here is a simple schematic showing both devices connected to your Arduino
